Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment technology, and in particular to a cardboard board die-cutting waste collection system. Background Technology

[0002] Cardboard boxes are used for packing and packaging in many fields. In cardboard box production, wide-width cardboard is first cut into cardboard sheets suitable for the unfolded dimensions of the box. These cardboard sheets are then fed to a printing press where information about the product to be packed is printed on the surface. Subsequently, die-cutting equipment trims and creases the edges of the cardboard to allow it to fold into a box. The die-cutting equipment generates a large amount of waste material, which needs to be collected. In existing technologies, waste is typically collected from only a single die-cutting machine, and then the waste from multiple die-cutting machines is centrally processed. For example, CN112871868A discloses a waste removal system for cardboard boxes, located between the die-cutting machine and the box-binding process. As the cardboard is conveyed from the die-cutting machine towards the box-binding process, waste material falls onto a conveyor belt, which transports the waste to a waste pool for crushing. For large-scale manufacturers, multiple printing presses and die-cutting machines can be matched to produce various types of cartons simultaneously. Each die-cutting machine is equipped with a waste removal system for cartons, which greatly improves equipment production and increases the equipment's floor space. Utility Model Content

[0003] The purpose of this invention is to propose a cardboard die-cutting waste collection system for collecting waste from multiple die-cutting machines simultaneously, thereby reducing equipment costs and floor space requirements.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A cardboard die-cutting waste collection system is provided for collecting cardboard waste generated by multiple die-cutting machines. The system includes a receiving trough, a receiving belt, a feeding belt, and a packing machine. The die-cutting machines are located on the side of the receiving trough, and the waste generated by the die-cutting machines enters the receiving trough via a guide slide.

[0006] The receiving belt is located inside the receiving trough, and the feeding belt is connected to the receiving belt. The feeding belt is used to transport the waste material into the baler.

[0007] The receiving trough is fixed with a material-blocking rubber sheet on each side. The bottom edge of the material-blocking rubber sheet abuts against the top edge of the receiving belt. A support plate is fixed inside the receiving trough. The support plate is used to support the working part of the receiving belt. Limiting grooves are provided on both sides of the support plate. The edge of the receiving belt extends into the limiting groove. The edge of the limiting groove abuts against the back of the material-blocking rubber sheet.

[0008] Furthermore, the top surface of the support plate is provided with a plurality of support rollers arranged in an array, and the support rollers are in contact with the bottom surface of the working part of the receiving belt.

[0009] Furthermore, the tail end of the receiving belt is located above the bottom end of the feeding belt, and the bottom end of the feeding belt is located inside the receiving trough;

[0010] A baffle is provided on one side of the feeding belt, and a scraper is connected to the top of the baffle. The top of the scraper is in contact with the feeding belt, and the side of the scraper is fixed to the receiving trough.

[0011] Furthermore, a flip-up vertical plate is provided on the side of the receiving trough away from the die-cutting equipment, and a flip-up horizontal baffle is provided on the side of the receiving trough close to the die-cutting equipment.

[0015] The top of the feeding belt is located above the collecting hopper.

[0016] The technical solution provided by this utility model can include the following beneficial effects:

[0017] In this technical solution, since the die-cutting equipment is located on the side of the receiving trough, the waste generated by the die-cutting equipment can directly enter the receiving trough through the guide slide. Then, the receiving belt transports the waste to the feeding belt, which in turn transports the waste to the baling machine. When the waste accumulates to a certain amount, the baling machine bales the waste into stacks, which can then be transported to a waste disposal plant for recycling. This cardboard die-cutting waste collection system can collect all waste from the printing and die-cutting lines, allowing for unified processing and significantly reducing equipment costs and floor space requirements.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is combined with Figures 1 to 5 This invention describes a cardboard die-cutting waste collection system according to an embodiment of the present invention.

[0026] The cardboard die-cutting waste collection system in this embodiment is used to collect cardboard waste generated by multiple die-cutting machines 01 simultaneously. The multiple die-cutting machines 01 can be located on the same side of the cardboard die-cutting waste collection system, or they can be located on opposite sides of the cardboard die-cutting waste collection system.

[0027] The cardboard die-cutting waste collection system includes a receiving trough 1, a receiving belt 2, a feeding belt 3, and a packing machine 4. The die-cutting equipment 01 is located on the side of the receiving trough 1, and the waste generated by the die-cutting equipment 01 enters the receiving trough 1 through the guide slide plate 02.

[0028] The receiving belt 2 is located in the receiving trough 1, and the feeding belt 3 is connected to the receiving belt 2. The feeding belt 3 is used to transport the waste material to the baler 4.

[0029] The receiving trough 1 has a retaining rubber sheet 11 fixed on both sides. The bottom edge of the retaining rubber sheet 11 abuts against the top edge of the receiving belt 2. A support plate 12 is fixed inside the receiving trough 1. The support plate 12 is used to support the working part of the receiving belt 2. Limiting grooves 121 are provided on both sides of the support plate 12. The edge of the receiving belt 2 extends into the limiting groove 121. The edge of the limiting groove 121 abuts against the back of the retaining rubber sheet 11.

[0030] In this technical solution, since the die-cutting equipment 01 is located on the side of the receiving trough 1, the waste generated by the die-cutting equipment 01 can directly enter the receiving trough 1 through the guide slide 02. Then, the receiving belt 2 transports the waste to the feeding belt 3, and the feeding belt 3 transports the waste to the baling machine 4. When the waste accumulates to a certain amount, the baling machine 4 bales the waste into stacks, and the waste stacks 03 can be transported to the waste disposal plant for recycling. The cardboard die-cutting waste collection system can collect all the waste from the printing and die-cutting lines and process it uniformly, greatly reducing equipment costs and the equipment footprint.

[0031] Specifically, the retaining rubber strips 11 on both sides of the receiving chute 1 are used to separate the waste material at the edge of the receiving belt 2 to prevent the waste material from getting stuck in the belt gap. The support plate 12 is used to support the receiving belt 2. Relative to the roller support, the support plate 12 ensures that the receiving belt 2 is reliably in contact with the retaining rubber strips 11. The limiting groove 121 of the support plate 12 limits the edge of the receiving belt 2 and also supports the retaining rubber strips 11.

[0032] Preferably, the top surface of the support plate 12 is provided with a plurality of support rollers 122 arranged in an array, and the support rollers 122 are in contact with the bottom surface of the working part of the take-up belt 2. The support rollers 122 are used to reduce the friction between the support plate 12 and the take-up belt 2. For example, the support rollers 122 are balls or rollers. It is understood that the support rollers 122 are located outside the limiting groove 121.

[0033] Understandably, the waste generated from cardboard die-cutting is shredded paper, which is lightweight and easily sticks to the conveyor belt due to static electricity. In order to ensure that all the waste on the receiving conveyor belt 2 can be transferred to the feeding conveyor belt 3, the tail end of the receiving conveyor belt 2 is located above the bottom end of the feeding conveyor belt 3, and the bottom end of the feeding conveyor belt 3 is located inside the receiving trough 1.

[0034] A baffle 13 is provided on one side of the feeding belt 3. A scraper 14 is connected to the top of the baffle 13. The top of the scraper 14 is in contact with the feeding belt 3. The side of the scraper 14 is fixed to the receiving trough 1.

[0035] Because there is a gap between the receiving belt 2 and the feeding belt 3, a baffle 13 is used to block the gap to prevent waste from falling into the installation space of the belts. A scraper 14 is used to scrape off the waste adhering to the surface of the receiving belt 2 to ensure complete unloading. For example, the scraper 14 is a rubber sheet or a plastic sheet.

[0036] In one embodiment of this utility model, a flip-up vertical plate 15 is provided on the side of the receiving trough 1 away from the die-cutting equipment 01, and a flip-up horizontal baffle 16 is provided on the side of the receiving trough 1 close to the die-cutting equipment 01. A horizontal baffle 16 is located on each side of the die-cutting equipment 01. The die of the die-cutting equipment 01 has an elastic pad to separate the cut waste and cardboard from the die. The die is arc-shaped and mounted on a roller, which rotates at a high speed. Therefore, some of the waste falls off in a splashing manner. Through the blocking action of the vertical plate 15 and the horizontal baffle 16, all the waste generated by one die-cutting equipment 01 enters the receiving trough 1. Furthermore, flipping the vertical plate 15 and the horizontal baffle 16 allows for easier access for maintenance personnel.

[0037] Furthermore, an inclined fan is provided on the upper part of the horizontal baffle plate, and the air supply direction of the fan is towards the receiving belt 2, ensuring that all paper scraps enter the receiving trough 1 and keep the production environment clean.

[0038] Preferably, a grating plate 17 is provided on the top surface of the receiving trough 1 located between two adjacent die-cutting machines 01. The grating plate 17 can improve safety and provide access for pedestrians.

[0039] In one embodiment of this utility model, the baling machine 4 includes a hopper 41, a transverse compression channel 42, and a wire guiding mechanism 43. The hopper 41 is located at the top of the inlet end of the transverse compression channel 42, and the wire guiding mechanism 43 is disposed on both sides of the transverse compression channel 42. The wire guiding mechanism 43 is used to guide the wire to the outlet end of the transverse compression channel 42. The top end of the feeding belt 3 is located above the hopper 41.

[0040] The waste material generated by the die-cutting machine is transported to the collection hopper 41 of the baling machine 4 via the receiving belt 2 and the feeding belt 3. When the amount of waste material in the collection hopper 41 reaches a certain level, it is pushed into the transverse compression channel 42 by the hydraulic extrusion plate, where the waste material is tightly compressed. Within the transverse compression channel 42, the waste material compressed at the front end is gradually filled by the compression from the waste material at the rear end, overflowing from the outlet end of the transverse compression channel 42 and pulling the steel wire 44 surrounding the outlet end. When the amount of waste material at the opening end of the transverse compression channel 42 reaches a certain level, the steel wire 44 can be cut to bundle the waste material into a stack, which is the waste stack 03. The steel wires 44 on both sides of the transverse compression channel 42 are then connected for bundling the next stack of waste material.
